Answer:
A
Step-by-step explanation:
We know the y intercept is positive so that eliminates choice D.
y = 3x^2 -2x+1
This does not intercept the x axis
y = 3x^2 -6x+3
= 3(x^2 -2x+1)
3(x-1)^2
This intercepts the x axis at 1
This is not the equation for the graph
y = 3x^2 -7x+1
Let x = 1
y = 3-7+1
= -3
This will cross the x axis, so this cannot be the graph
No. For example,
gives you a 2, which isn't a recurring decimal! You can try this for all sorts of multiples of 9 and you will see that they do not give you recurring decimals. However, there are some, e.g.
which gives you 1.1111111....
Hope this helps!
D.) I and II Only.
1 degree increase in Celsius changes 9/5 or 1.8 degree change in fahrenheit and inverse is also true.... 1 degree increase in Fahrenheit 'cause 5/9 or 0.55 in Celsius
Hope this helps!
When you have a polynomial function, and you need to graph it, you need to find- y intercept (the constant at the end) zeroes( factor equation and set factorsequal to zero) end behavior( if the highest exponent is even, then if the leading coefficient is positive both sides continue up, if the leading coefficient is negative both sides continue down. If the highest exponent is odd, then if the leading coefficient is positive left side continues down, right side continues up, if the leading coefficient is negative then visa versa.) and multiplicity( if the same factor occurs multiple times- if it occurs an odd number of times, then the graph passes the x axis, if it occurs an even number, then it merely touches).
Hope I helped!
